Abstract

See full text

Apparatuses and methods for providing internal power voltages are described. An example apparatus includes a first, second, and third clamp circuits, and a clamp control circuit. The first clamp circuit is configured to receive a first external power voltage and provide a first voltage drop to provide a first internal power voltage. The second clamp circuit is configured to receive the first external power voltage and provide a second voltage drop to provide a second internal power voltage, wherein the first voltage drop is greater than the second voltage drop. The third clamp circuit is configured to receive a second external power voltage and provide the second external power voltage as the second internal power voltage when the second external power voltage is activated. The clamp control circuit is configured to activate the third clamp circuit when the second external power voltage reaches a trigger voltage level.
